DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: an air source heat pump that is convenient for pipe docking, comprising a heat source pump body 1, a docking seat 2 is fixedly connected to one side of the heat source pump body 1, and a moving component 3 is provided at the bottom corner of the heat source pump body 1;

[0025] The interior of the docking seat 2 is fixedly connected with a fixed sleeve 204, and the fixed sleeve 204 is sleeved on the outside of the movable sleeve 205. The middle inner wall of the movable sleeve 205 is fixedly connected with a strong magnetic block 206, and the strong magnetic block 206 divides the inside of the movable sleeve 205 into a first chamber 205a and a second chamber 205b. The inner wall of the first chamber 205a is provided with two holes 207, and the outer circles of the two holes 207 are provided with limiting walls 208. The middle part of the limiting wall 208 is movably connected with a steel ball 209, and the steel ball 209 is fitted with the docking pipe 2010. Four locking claws 201 are hinged at one end of the docking seat 2 away from the heat source pump body 1. The outer sides of the four locking claws 201 are all provided with external threads, and the outer sides of the four locking claws 201 are threadedly connected to the inside of the threaded cover 202 through the external threads. The inside of the threaded cover 202 A sealing ring 203 is fixedly connected to one end, and one side of the sealing ring 203 is fitted between one end of the four locking claws 201. The docking tube 2010 is divided into three sections, wherein the end inserted into the docking seat 2 is the extrusion section, the part fitted with the steel ball 209 is the clamping section, and the exposed part is the tube body section. The diameters of the three sections of the docking tube 2010 are, from large to small, the tube body section, the extrusion section and the clamping section. A spring 2011 is provided in the middle of the second chamber 205b, one end of the spring 2011 is connected to one side of the strong magnetic block 206, and the other end of the spring 2011 is connected to the inner bottom surface of the docking seat 2, and an electromagnetic ring 2012 is provided on the inner bottom surface of the docking seat 2. The contours of the movable sleeve 205 and the fixed sleeve 204 are consistent, and the diameters of the movable sleeve 205 and the fixed sleeve 204 away from the heat source pump body 1 gradually decrease.Before the docking tube 2010 is docked with the external pipe, the internal thread of the threaded cover 202 is not connected to the external thread of the four locking claws 201, and the docking tube 2010 is inserted into the docking seat 2. During this process, when the extrusion section contacts the two steel balls 209, the distance between the two steel balls 209 cannot allow the extrusion section to pass. At this time, the extrusion section will first push the steel ball 209 toward the bottom of the docking seat 2, and a part of the steel ball 209 will be stuck in the hole 207. When the steel ball 209 moves, it will drive the movable sleeve 205 to move, thereby squeezing the spring 2011 through the strong magnetic block 206. When the movable sleeve 205 moves toward the inner bottom of the docking seat 2, the gap between the movable sleeve 205 and the fixed sleeve 204 increases, and the steel ball 209 will continue to be squeezed into the hole 207 by the extrusion section of the docking tube 2010 until the distance between the two steel balls 209 is The extrusion section end can be passed, and then the steel ball 209 will contact the clamping section of the docking tube 2010, loosening the docking tube 2010, and the strong magnetic block 206 will rebound under the action of the spring 2011, and the strong magnetic block 206 will drive the movable sleeve 205 to reset, and the gap between the movable sleeve 205 and the fixed sleeve 204 will gradually decrease. The two steel balls 209 will also gradually approach until they are fitted with the clamping section of the docking tube 2010, and the docking tube 2010 will be stuck in the docking seat 2, and finally the threaded cover 202 and the external thread of the locking claw 201 are tightened. At this time, the locking claw 201 will be tightly attached to the pipe body section of the docking tube 2010, so that the docking tube 2010 can be locked in the docking seat 2. During the whole process, the docking tube 2010 needs to be inserted into the docking seat 2, and then the threaded cover 202 is tightened to complete the docking with the external pipeline, thereby improving the docking efficiency of the pipeline.

[0026] In this embodiment, Figure 1 and Figure 2 As shown, the mobile assembly 3 includes a mounting block 301 fixedly connected to the bottom corner of the heat source pump body 1, a locking pin 302 is threadedly connected to one side of the mounting block 301, the locking pin 302 is inserted in the middle of the locking hole 303, the locking hole 303 is provided on the side of the caster 304, the caster 304 and the inner wall of the mounting block 301 are rotatably connected through a connecting shaft, the number of the locking holes 303 is several, and the several locking holes 303 are equiangularly distributed on the side of the caster 304. By setting the caster 304, it is convenient to move the heat source pump body 1 to a designated location, and the locking pin 302 is twisted and inserted into the locking hole 303 on the side of the caster 304, so that the caster 304 can be locked to limit the movement of the caster 304, without the need for other moving tools, and the movement is more convenient.

[0027] The working process of the utility model is as follows:

[0028] like Figures 1 to 4As shown, when in use, first move the heat source pump body 1 to a designated location via the caster 304, then twist the locking pin 302, insert the locking pin 302 into the locking hole 303 on the side of the caster 304, and the caster 304 can be locked to limit the movement of the caster 304, without the need for other moving tools, making movement more convenient; when it is necessary to dock with an external pipeline, insert the docking pipe 2010 into the docking seat 2, and during the insertion process, when the extrusion section of the docking pipe 2010 is in contact with the two steel balls 209 When in contact, the distance between the two steel balls 209 is too large for the extrusion section to pass through. At this time, the extrusion section will first push the steel ball 209 toward the inner bottom of the docking seat 2. A part of the steel ball 209 is stuck in the hole 207. At this time, the steel ball 209 will drive the movable sleeve 205 to move when moving, thereby squeezing the spring 2011 through the strong magnetic block 206. When the movable sleeve 205 moves toward the inner bottom of the docking seat 2, the gap between the movable sleeve 205 and the fixed sleeve 204 increases, and the steel ball 209 is pushed toward the inner bottom of the docking seat 2. 09 will continue to be squeezed into the hole 207 by the squeeze section of the butt tube 2010 until the distance between the two steel balls 209 is enough for the squeeze section end to pass through, and then the steel balls 209 will contact the clamping section of the butt tube 2010, loosen the butt tube 210, and push the strong magnetic block 206 to rebound under the action of the spring 2011. The strong magnetic block 206 drives the movable sleeve 205 to reset, and the gap between the movable sleeve 205 and the fixed sleeve 204 gradually decreases, and the two steel balls 209 will gradually approach each other. The butt joint 2010 is then locked in the docking seat 2, and the threaded cap 202 and the outer thread of the locking claw 201 are finally tightened. At this time, the locking claw 201 will be in close contact with the pipe body section of the butt joint 2010, so that the butt joint 2010 can be locked in the docking seat 2. During the whole process, the butt joint 2010 needs to be inserted into the docking seat 2, and then the threaded cap 202 can be tightened to complete the docking with the external pipe, thereby improving the docking efficiency of the pipes.
